- the shielding effect of the moving member 250 and the moving member 250 can reflect the characteristics of the light beam 222 to the second photosensitive element 240 and the third photosensitive element 260, so that the body 210 can generate different light receiving combinations in different oblique directions.
- the tilt sensor 200 of the present embodiment can receive the state of the light beam 222 through the first photosensitive element 230, the second photosensitive element 240, and the third photosensitive element 260, thereby reversing the tilt direction of the body 210.
- the moving member 250 is a ball size substantially equal to or smaller than 0.5 mm and larger than 0.1 mm, the light emitting diode 220, the first photosensitive element 230, the second photosensitive element 240 and the third photosensitive element 260 are crystallized on the same plane.
- the thickness of the tilt sensor 200 can be effectively reduced to 0.8 mm, or even smaller, and the characteristics are light, thin and short.
- the tilt sensor of the present invention has at least the following advantages.
- the moving member is inclined with respect to the tilting direction of the tilting sensor, and is moved in different directions by the relationship of gravity, and is tilted by the blocking effect of the moving member and the characteristic that the light beam is reflected by the moving member.
- the detectors generate different light-receiving photosensitive elements in different oblique directions, and then receive the state of the light beam through the photosensitive elements, thereby reversing the inclination direction of the tilt sensor.
- the moving member is a ball having a diameter of 0.5 mm or more and more than 0.1 mm, and the light emitting diode and the photosensitive member are fixed on the same plane, so that the thickness of the tilt sensor can be effectively reduced.
